feat(briefwechsel): bump row typography and drop relative-year chip

The 168px-tall thumbnail tile was dominating rows where the text
column only rendered at text-xs / text-sm — visually the right
column sat half-empty. Three changes:

- Title: text-sm → text-lg
- Summary: text-sm → text-base
- Meta + tag chips: text-xs → text-sm

And remove the "vor N Jahren" chip entirely. The documentDate
in the meta row already carries the temporal context and the
chip was adding visual noise without new information.
